Chinese animal feed company Tongwei Co Ltd will boost its buying of Canadian canola meal by up to C$240 million ($242 million) annually by 2015, after China banned meal from India late last year.

Canada's agriculture minister Gerry Ritz, who announced Tongwei's plans on Tuesday during a visit to China, said its purchases could be worth C$900 million over the next decade.

Chinese oilseed traders have expected increased imports of canola and canola meal from Canada, the top canola exporter, after China halted purchases of Indian meal because some cargoes were found contaminated with a dye used to brand grain sacks.

"This certainly puts some long-term stability in that (industry)," said Brian Wittal, agriculture analyst at Pro Com Marketing in Alberta. "If we can maintain and hold onto that market, that will be the key thing. The big thing is whether India can adjust and get back into (China)."

Tongwei's plans are a result of research funded by the Canadian government to demonstrate the quality of canola meal for Chinese dairy and aquaculture processing companies, Ritz said in a statement from Chengdu, China.

The Grain Growers of Canada farm group, which is travelling with Canadian officials in China, said Tongwei could buy up to 1 million tonnes of canola meal within five years for aquaculture. The Canola Council of Canada, also on the trip, pegged the value of Tongwei's plans at up to $300 million, including C$60 million worth of canola meal it already buys annually.
